16 Claims.

This invention relates to room heating appliances, and more particularly to that type of appliance designed for use in a cabinet and known in the art as convectors. More specically, the invention is for an improvement in convectors of the type shown in my copending applications Serial No. 513,883 now Patent No. 1,912,556, dated June 6, 1933, and Serial No. 514,164, now Patent No. 1,888,545, dated November 22, 1932.

In said copending applications I have shown a convector comprising a plurality of sections arranged side-by-side, each section comprising an inclined barrel having a header portion at the` top and a header portion at the bottom, and having a plurality of heat dissipating fins on the side faces thereof. These fins form, in effect, a number of relatively short vertically extending air passages, the ns being inclined with respect to 2O both the longitudinal and transverse axes of the barrel. With this arrangement the air rises up on the underside of the convector, passes through the channels defined by the fins, and discharges on the upper side of the convector. The whole structure is enclosed in a casing forming a flue or draft head. An elect is produced by such an arrangement comparable to that of a horizontally disposed convector having fins thereon forming vertical air passages.

., At the same time, by reason of the slope, the

cabinet or housing for the convector is of relatively less depth than would be required for a convector having horizontal barrels with vertical ns similarly placed.

In a convector ofthis type it is desirable to provide as much heat radiating surface in a cabinet of given dimensions as possible. At the same time, provision must be made for connecting the convector into the hot water or steam heating 4 system together with the usual valves, pet-cocks,

and sometimes humidiiiers.

The present invention provides an end section for use with convectors of this type which are adapted for connection into heating systems cf various types, permitting the pipes to go into the bottom of the convector or into the ends at either the top or bottom, which are arranged with iins for cooperation with the other sections of the convector and which permit the piping to be positioned in the center of the cabinet instead of forwardly or rearwardly of the center, and which provide a large heat dissipating surface. Instead of providing less heat dissipating surface at the ends of the convector than in the other sections, they provide more.

The invention, moreover, is adapted to either convectors of the single tier type or convectors of the multiple tier type.

The invention may be readily understood by reference to the accompanying drawings in which Figure 1 represents, in elevation, a convector of the single tier type embodying my invention;

Figure 2 is an end elevation of the end section, 65 looking at the outside of the section; i

Figure 3 is a transverse horizontal section in substantially the plane of line III-III of Figure 2;

Figure 4 is a view similar to Fig. 2 showing an end section for a multi-tier convector;

Figure 5 is a side elevation of the end section shown in Fig. 4; and

Figure 6 illustrates more or less conventionally a typical installation for a multi-tier convector.

Referring first to the embodiments shown in Figs. 1 to 3, inclusive, the convector unit comprises a number of intermediate convector sections 2 which are preferably of the type shown in my Patent No. 1,888,545, Vcharacterized by the provision of upper header portions 3, lower header portions 4 connected by thin flat barrels 5 which are turned edgewise, and which are provided on each side face thereof with an upper series of ns and a lower series of fines which are staggered with relation to each other. In Figure 1 these fins are designated 6, and are staggered in a manner generally similar to the dotted line position of the iins appearing in Fig. 2 of the drawings, and which will be hereinafter more fully described.

As stated above, this construction of the sections 2 is disclosed and claimed in my said Patents 1',888,545 and 1,912,556. The convector sections 2 are supported between end 'sections 7, which sections are similar to each other, but 5 which are reversed by reason of their being positioned at opposite ends of the convector. Each of the end sections 7 comprises a hollow rectangular panel having an outer face 8 and an inner face 9, the hollow interior of the panel forming a vertical chamber designated 10. On the outer face 8 near the top of the panel is cast a boss 11 tapped to receive a plug 12, the plug 12 being removable so that when desired a steam or water pipe can be screwed into this opening, 105 which communicates with the interior chamber l0. The boss 11 is centered on the vertical center line of the section. At the bottom of the section there is cast another boss 13 having a downwardly extending portion 14. The boss 13 and 110 the portion 14 each have an interior passageway opening into the chamber 10, and each has a threaded opening for the reception of a plug 15 or of a water or steam pipe. I have shown plugs in all of these threaded openings in the bosses 11, 13 and 14, but it will be understood that in differentl heating plants diiferent .openings .would be use-d :for steam-pipes or waterrpipes, in which case the plugs at the desired points would be replaced by pipe connections. On the inner face of each of the end sections on the upper rear corner thereof there is a boss l5 which is faced to contact with the header portion 3 of the-.adiacent intermediate section. This boss .16 hasan opening to receive a force nipple of :the .type commonly employed in connecting radiator-sections, and which is not shown, whereby water or steam may circulate from the chamber i1`0 in .the end panel into or out of the intermediate sections. Diagonally opposite the boss 16 on the 'inner face .ofthe endsectionis afsimilarboss l1'7. :Locationpf the :boss v17 is therefore,.in -thisparticular structure, near the .hottom-ofthelend sec- 'ztionfandiin front lof :the verticakeenter line of tthefsection. This7boss, likefthe .boss.l6,is. shaped and faced for cooperation with the corresponding headerportion '4 :of the ,adjacent intermediate sectipn.

.The 'width of the end .sections corresponds approximately Lto the width of the interior of `the rcabinetain `whichtliefconvector is adapted to be housed, .and the fpositions eof y-the bosses 16 and 1'7 assures the intermediate sections being sloped iupwardlyand rearwardly .for ithe purpose rdescribed in my `'said copendi'ng applications and ipatents, :and Avslheres'slope .in =this .direction -isfdesired. Cast on the inner face of each `of the .end sectionsifareg'heatrdissipatingnsfadaptedfte-regis- .ter `with `gthe iins :of ythe adjacent 'intermediate sections. .In the convector illustrated, I have showntwoseries'of ns .1-8 and 19 fon-opposite sides tof the 'line offcentenof thefbosses 16'. andi?, :the .ins of :one -series being-staggered or offset :with'respect to :the inns of `the other series, the .i'lns being ucoextens'ive lwith :and -`adapted 4to regislter .with .theinsxof '.theadjacent intermediate esecrtion.

'.Thecendfsections .have -lu-g portions l20 at .di- Lagonally opposite 'corners ffor tie bolts 21 for holding 'the :assembly together. At the bottom vof feach end .section :are aendwise :projecting lugs .22 .which areinternally threa'dedto `receive the fthreaded .vends of ysupporting legs .23; .24 designates :lock V.nuts on the threaded upper ends vofthese legs.

Each ofthe end sections does not exceed in its;overall :widthzthe space required lfor one Aof Ythe intermediate sections. This-.is .of advantage, because yin .estimating `.required .radi-ation, the number `of .sections may 'be fspecied Awith the knowledge th'at vas .far =as .width .is concerned :the 'end sections merely :replace :intermediate sec- 1tions. Theiin `orextended area on vthexendrsections is smaterially less than the extended area on "the -intermediate sections, land vthe placing of ns on `thevouter -fa'ces of `the end sections would be 'of trelatively little -value compared with the :increased weight, because such `i'lns would have Ano adjacent ns for cooperation therewith, with the Aresult that there would be no substantially 'closed air passages provided Afor a relatively high Velocity fair circulation between the ns. 'Compensation-isftherefore effected by reason of the fact't'hatithe end sections-providea relatively .to assure .the proper slope of the convector.

.a .maximum vof iin space.

greater prime surface for the dissipation of heat than do the intermediate sections.

In order to keep the overall width of the end sections the same as the overall width of the intermediate sections and still provide for the necessary pipe connections in the portions 14, the portions .14 are .offset inwardly toward the inner face of the convector, thus enabling .the portions 14 to be of the diameter necessary for standard Ypiping used in heating systems. and still main- .tain the portion 14 within the overall limits of the end sections.

.The outer faces of the end sections may also vbe provided with such additional bosses as may 'be required for pet-cock connections or humidier connections. In the upper part of the section above'the boss 11 is a small boss 25, in which I .have :showna .plug 26. The plug 26 may be replaced by a pet-cock or an air escape valve of some kind. The outer face of the section may also .be .provided with a boss .27 v.in which I have showna .plug.28. Aypipermaybe substituted for theplug .2g-where connectionis tobe made from the .heating ysystem to yan air valve, as is Awell understood by v those skilled in .this art.

Theadvantages of the invention residein the provision of .a channel-.like .end :section serving to substantially'close the ends of theconvector, having fins-,thereon which register and cooperate withthe fins of theadjacentconvector sections and having nipple ports thereonso positionedas .A furtheradvantage .is -that l.provision is made for bringing the .pipesinto either .the bottomor .the loweroutside face .or the .upper outside .face .of the. convector with such pipes at the vertical centerof the convector instead of forwardly or rearwardly, as would be .necessary .if the `pipes Yhad ,to .be connected directly tothe .toporbottorn of .the vinclined intermedi-ate sections. A

.further advantage is that the end sections provide .a largeprime heatingsurface to compensatejfor the relatively .smaller extended heating surface .and vin the .fact that the overall .width ,of .the .end ,sections .is approximately ,the same as .the voverall width .of any of the.intermediatesections .-A ystill .further .important .advantage .of .this type of end section is that theconvector sections, which .have relatively .thin ^fragile fins, lie .entirely .within .the `area of ,the .rectangular .end panels, vas .will be evident .from Tan inspection .of Fig..2, `with .the .result that when .the convectors are boxed for shipping, orare being transported,

.there .is little likelihood .of :the convector being damaged, .particularlythe iins, because all of .the fins lie within .the connes .of .the .rectangular panels.

lUnder .some conditions itis V.desirable to arrange .the convectors intiersso as toprovide in a relatively small compact .unit a .convector having a .relatively large heat'dissipating area with .For such an arrange- .ment .theconstruction shown inFigs. 14 and i5 is .employed. .'I have illustrated an end sectionin ,these iigures for a unit having Lthree .tiers .of .convectors The general-construction ofthe end section is not materially different `fromthat previously'described. It comprises a substantially *rectangular hollow panel `30lhavingan outerfface 31 and an inner face 32. The outer face -is 4provided with ybosses at 33, 34 vand 35 which vmay ybe vplugged,for through which aconnection maybe made tothe water or steampipes-of the isystem. The sections are relativelyahigher, howeverythan the end sections shown in Fig. 1. On the inner face thereof are a plurality of pairs of bosses, the bosses of each pair being diagonallydisposed with reference to one another.

In the construction shown in Fig. `4 the first pair of bosses comprises an upper boss 36 and a lower boss 37, the boss 37 of course being on the inner face of the panel and being similar to the bosses 16 and 17 in that they are adapted to register with the header portions of the adjacent convector sections. The second pair of bosses 38 and 39 are similarly constructed and are equi-distantly spaced below the bosses 36 and 37, respectively, so that a second tier of convectors below the rst one will besubstantially parallel with the rst tier. The third pair of bosses 40 and 4l are similar to 36 and 37 and are spaced below the bosses 36 andV 37 an equal distance so that a third tier of convector sections may be placed below the second and be parallel therewith.

On the inner face of these panels are cast a series of ns 42, 43 and 44 arranged to register with the ns of a correspondingly positioned convector and to complement the fins of adjacent convector sections, the upper series of ns 42 being disposed between the diagonally disposed nipple ports 36 and 37, the middle series of fins 43 being disposed between the diagonally varranged nipple ports 38 and 39, and the lowermost series of fins 44 being located between the diagonally disposed nipple ports40 and 41.

I have shown in Figs. 4, 5 and 6 bosses 55 on the inner face of the end section adjacent the bottom thereof and oiset with respect to the vertical center line of the section and with respect to the boss 35. This arrangement permits of the connecting pipe to come up on the inside of the end section, as shown in Fig. 6, instead of on the outside. This has an advantage in that the enclosure need only be as wide 'as the` convector unit, and no space beyond the end sections has to be left for pipes and pipe connections. While I have not shown a connection boss so located in the construction shown in Figs. 1 and 2, it is apparent that this feature may be included on the end section for a single tier convector as well as on an end section for a multiple tie convector.

The provision of a number of parallel tiers of convectors arranged in spaced relation gives a greater effective distribution-of the extendedarea provided by the iin surfaces than would be obtainable in a single convector having a total vertical height equal to the height of the three tiers placed one on top of another.

In Fig. 6 I have shown a typical embodiment of a heater of the multiple tier type in which the convector unit or heater designated is disposed in an enclosure 51 constituting a vertical flue, with an air inlet opening near `the bottom at 52 and discharge through a grille 53 at the top. The enclosure is illustrated as being built within a seat such as is commonly provided in railway stations and similar public places. The enclosure is of suflicient height so as to furnish a considerable draft head so as to insure the travel of air through the convector at a relatively high velocity, more effective heating being secured through the heating of a larger volume of air in a given period of time to a lesser degree of temperature than by heating a smaller volume of air to a relatively higher temperature inthe same period of time, the former method securing a onally disposed series of ns on the inner better and more even diffusion of the heat through the room.

It will be understood that while I have shown three tiers of convectors in the multiple tier type, this is merely an arbitrary number, and that a different number may be employed according to the particular installation for which the unit is designed.

The end sections in the multiple tier type of convector have all of the advantages of the end section described in connection with the single tier convector shown in Figs. 1 to 3, inclusive. Instead of showing in the multiple tier convector a connector similar to the connector 14 of Fig. 1, I have shown a connector 46 on the inside face of the panel offset with respect to the vertical center line thereof, this being desirable for the particular installation shown in Fig. 6, but it will be understood that where desired the downwardly opening center connector 14 of Fig. l can be substituted for the arrangement shown in Fig. 4.

While I have shown certain particular preferred embodiments of my invention., it will bev understood that various changes and modifications may be made therein without departing from the spirit of my invention and the scope of the following claims.
